Please turn on/enable highlighting. Often when quoting someone, I am responding to a specific portion of their post and highlighting would be the "right" way to do that rather than changing the color/bold/underline of the portion of the quote. Even if it's just enabling the BBCode for highlighting would be great:
[highlight={COLOR}]{TEXT}[/highlight]
so this would work:
[highlight=yellow]this text is highlighted[/highlight]
[highlight={COLOR}]{TEXT}[/highlight]
so this would work:
[highlight=yellow]this text is highlighted[/highlight]
